Molecular Anthropology

Genetic differences among
modern human people groups should provide evidence for the spread of
humanity through the world. Those groups that exhibit the greatest genetic
dissimilarity should represent the oldest populations. Therefore, the
geographic location for the origin of modern humans can be determined from
these studies. There is some interplay between the date of the last common
ancestor and the population size of the species. The smaller the assumed
population size results in an earlier date for the last common ancestor.
Therefore, neither value can be absolutely determined.
